This invention relates generall tofasten in devices and, more particular y, to a carwith the boards and fastening means in mm new and useful device adapted es cially for securing or fastening materia such" as beaver board, linoleum, and other such sections or the like to studding or other frame-work in the formation of walls and partitions, to flooring, or upon other. suraces or supports. a

My present invention has for its chief object the provision of means in the form preferably of suitably elongated metallic strips of simple and inexpensive form and construction which may be readily secured or otherwise fixed to the studding, flooring, or other surface or support and by which panels'or. sections, such as, for instance, sections or strips of beaver-board, linoleum or the like, may be conveniently, uickly, and efliciently secured and held in p ace and the joints or seams therebetween concealed.

And with the above and other objects in view, m invent-ion resides in the novel features 0 form, construction, arrangement, and combination. of parts hereinafter. de-' scribed and pointed out in the claims.

In the accom anying drawings,--

Figures- 1 and 2 show in. perspective and in preferred form co-operative fragments of material-securing and joint-concealing devices or stri embodying my invention;

Figure 3 s ows in section a fragment of a wall-studding, a fastening means 0 preferred form of my invention, the latter bein disposed with relation to the 'studding an boards reparatory to final securement of the boar s;

Figure 4 is a view similar to Figure '3 final board-securing and joint-concealing position;

Figure 5 is a view similar to Figure 3 illustrating, however, a slightly modified form of material fastening means embodyin my invention; and

viigure 6 is aview similar to Fgure 5 with the boards and fastening means in final board-securing and joint-concealing position.

Referring now more in detail and b reference characters to the drawing, designates the so-called clinchable member and B the so-called material-engaging member of the preferred form of my new fastenin device.

e member A is constructed of suitable air of wall-boards, and

connection, and to such end C desi number of nails is used. It is also bendable sheet metal,--isnormally approximately of C-sha in end view and section, as best seen in grall includes'a generally fiat base wall 1,

igures 1 and 3, and r" roun ed or arcuated side-walls 2, 28nd infrom and turned flanges 3, 3, suitably spaced dis osed i'n'overhangmg relation to basewe 1 1 and also suitably spaced fromeach other, at their free margins. wise and approximately centrally between the side walls 2, base wall 1 is provided with a series of spaced nail-accommodating per- L forations or openings4. y The member B is. lso constructed of suitable bendable sheet metal, is normally approximately of T-shape in end view and section, as. seen in Figures 1 and 3, and includes, the material of which it is com being doubled upon itself, a double-we rib or web 5 and double-wall oppositely disposed flanges 6, 6, presented outwardly from an end of and at an angle to the web fi, the

wall-members of rib or web 5 at their'lower 6 arcuately are outwardly, as shown, and the flanges 6 being downwardl ron d as at 8, 8, lengthwise along their ou ter Emir .It'will be understood that the mem re A and B are formed by rolling or other suitable operations in suitable sizes and dimensions and cut to lengths as For pur my new astening strips in wall-forming te d' te t ddi f ding inrmeia su ngor oauil' wall or partition, and Dffif designate panels or sections of wall forming-material, such as, for instance, commercial beaver board, adapted for location and for securement upon the studding wall or partition. As 15 common, the wall boards or sections D are uniform] presized and are ordinarily of reetan ar-oblong she e.' Ordinarily, such we -boards are butttted over a frame element and secured by nailing through the boards into the frame element. Obviously, where headed nails are employed, the atest precision and skill must be exercise to avoid a .grotesque arrangement of nail heads and ob ses of illustration, I here show a5 C to complete the 7 viously further where headless or finish nails. are employed, the holding, at best, is

insecure, even though a relatively great uite common today that in the handling 0 the or partition presents unsightly scams or,

wall-boards in commerce, much damage is done the margins-hence, the ordinary wall joints between boards. e.

my present invention, 'a stri or memberA Y is first lengthwise secured ynails or the like 9 flatwisc at its base-wall 1 to and u n the studding C. The boards D are en batted upon the studding G and over the secured or fixed strip or member strip" or member B is then disposed with its rib 5 intermediate the abutting ends of the boards D with its rib-extensions T restingv in the channel, of strip A and with its 4 flanges 6 overlapping upon the adjacent ends of the boards D. By means then of suitable pressure applied u on the member B through a hammer or ot er suitable tool (not shown the ribfextensions 7 are forcibly s rea outwardly and clinched down upon e base-wall 1,the flanges 2 clinched downwardly upon and into impinging en-' gagement with'the so spread and clinched rib-portions 7, and, at the same time, the

ribs 6 embedded into engaging relation with the boards D. Thus the member B is so.-

curely fastened to the fixed strip A' and, through co-o rative clinching engagement between the anges 6 and the ribextensions 7 the boards D to the 'studding C.

' "As shown in Figures 5 and 6, I ma as a modified form in the. use of my new asten- "ing strips, dispense with the strips or memhere A, slightly normally s ace the walls of the rib 5 and the walls 0 the flange 6'.of1 "the members B and dispose the securing with strips of B ty approximately against the rib 5'.

nails 9' with their heads and shanks intermediate the walls of the rib and flanges of the strips B, In the construction of a wall ,the strips B' are suitabl disposed lengt wise upon, and partially y means of the nails 9' secured to, the studding C. The boards D are then fitted upon the studding with their adjacent ends disposed under the flanges 6 and abpjttiing n er ' suitable pressure then applied upon the strips B, the rib-portions or extensions 7' '50.

. rectly upon the stu din will be similarly s read and clinched diand the boardsD at their edges will be clinched and securely held'between the flanges 6 and the so spread and clinched rib-extensions 7', the nails 9' atthe: same time being driven home and the strip firmly attached to the studding.

-. My .newf'strips may be readily and 1nex-' pensively manufactured, and by theuse of i strips in accordance with my invention, I am enabled to quickly, conveniently, tightly, se-

' purely, .1 boar the like in place and bind and fastenwallother such sections or form, a substantially seamless, smooth wall, partition, floor-cover ing, or the like, the margins of the several and eflicientl linoleum, an

- extensions projecting sections being covered and the joints therelike, .to more positively resist combustion, In the construction of a wall according to.

nails or other fastenin means of the sections are concealed, an orvother surfacing material at seams 1S obviated.

- Iam aware that changes in the for-m, construction, arrangement, and combination of cracking of paper.

the several dparts of my new fastening strip may be ma and substituted for those herein shown and described without departing from the nature and principle of my invention'.

Having thus described my invention, what I claim and desire to secure by Letters Patcut is: p I v 1. Abutting material fastening and joint concealing means including a first sheet,

metal strip of C-shape in section adapted for disposition flatwise under the abuttin material wit-h its flanges presented upwar ly and the opening therebetween in approximate alignment with the joint between said abutting material, and a second sheet metal stri or substantially vT-shape comprising a we oppositely disposed flanges presented outwardly from an end of and at an an le-to.

the web, and oppositelfy disposed clinc able mm the opposite end of the web, the second strip being adapted for disposition with its web between said abutting material, its flanges flatwise engaging the upper marginal edge-portions of sald abutting material, and its said extensions projecting through the openin and beneath the flan es of the first strip, is e two strips being a apted under pressure for interlocking engagement with the extensions of the second strip clinched by the'flanges of the first stri and said abutting material clinched irectl between the flanges'of the first and secon strips.

2. Abutting material fastening and joint concealing means including a first sheet metal stri of C-shape in section adapted for disposition flatwise under the abutting material withits flanges presented upwardly and the opening therebetween in approximate alignment with the 'oint between said abutting material, a secon sheet metal strip of substantially T-shape comprising a web, oppositely disposed flanges presented outwardly from an end of and at an angle to theweb, and oppositely dis osed clinchable extensions projecting from t e opposite and ion of the web, the second strip being adapted for disposition with its web between said abutting material, its flanges flatwise' engaging the upper marginal edge-portions of said abutting material, and its said exten sions projectingthrou h the opening and beneath the flanges of t e first strip, the two strips being adapted under pressure for inand at an angle to the walls of the web, and

oppositely disposed extensions rojecting from the opposite end of the wa ls of the web for clmchable co-operation with said flanges in engaging the abutting.- material, and a wall-engagin nail havin the upper portion of its 3 m5; disposed tween the walls of the web;

In testimony whereof I hereunto aflix my signature.
